Place the butter and cream cheese in your chosen microwavable mug. Microwave on HIGH for 20 seconds.
Add the remaining ingredients except the cinnamon and brown sweetener to the mug and mix well.
In a seperate small bowl mix together the cinnamon and brown sugar. Pour the cinnamon sugar mix over the mug cake batter. Use a knife or back of a fork to slightly mix the cinnamon and sugar into the batter using a spiral motion.
Microwave on HIGH for 1:20 seconds minute.
Mix together the cream cheese icing and spread it over the cop of your cinnamon roll mug cake while it is still warm. Enjoy!
Please adjust the microwave cooking times according to the strength of your microwave.My microwave is pretty powerful and only requires 1 minute, but most standard microwaves may require the 1:20 as stated in the recipe.No microwave? No problem. Simply bake at 180C/350F in a cupcake case or muffin tray for 12 minutes.
